The atomic number is the number of protons.
To calculate the number of protons in an atom, use the atomic number (Z), which represents the number of protons. The number of neutrons can be calculated by subtracting the atomic number from the mass number (A = Z + N). Electrons are the same as the number of protons in a neutral atom.
you look at either the atomic number or the number of electrons. That's the number of protons.
It is the number of positely charged nuclear particles ( protons ).
equal to number of protons
protons plus neutrons = atomic number
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the atomic mass number is the number of protons/electrons in an atom
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
You can calculate the number of neutrons an atom has by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are the difference between these two values.
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
